so... hmmm if you check the first picture below, for 2)we could use the proportions of those small, medium and large similar triangles like [tex]\bf \cfrac{small}{large}\qquad \cfrac{x}{12}=\cfrac{6}{x}\impliedby \textit{solve for "x"} \\\\\\ \cfrac{small}{large}\qquad \cfrac{z}{18}=\cfrac{6}{z}\impliedby \textit{solve for "z"} \\\\\\ \cfrac{large}{medium}\qquad \cfrac{y}{12}=\cfrac{18}{y}\impliedby \textit{solve for "y"}[/tex]now.. for 3) will be the second picture below[tex]\bf \cfrac{large}{medium}\qquad \cfrac{x+10}{2\sqrt{30}}=\cfrac{2\sqrt{30}}{10}\impliedby \textit{solve for "x"} \\\\\\ \textit{now, because you already know what "x" is, we can use it below} \\\\\\ \cfrac{large}{small}\qquad \cfrac{z}{x}=\cfrac{x+10}{z}\impliedby \textit{solve for "z"} \\\\\\ \textit{and let us use "x" again below} \\\\\\ \cfrac{small}{medium}\qquad \cfrac{y}{10}=\cfrac{x}{y}\impliedby \textit{solve for "y"}[/tex]
